Drawing of square section rod from round bar can be done with two die shapes. In the first die shape, deformation starts from corners of the square and in second die shape, deformation starts from sides of square. This article has compared the drawing force for both die shapes and as a result optimum die shape was determined. Due to complexity of metal flow inside the die, analyzing of actual p...

This paper presents a new framework for recovering superquadrics with global deformations from multi-view real range data. The framework aims at improving confidence and accuracy of recovered models by utilizing multiview information, and consists of the initial superquadric model recovery, view registration, view integration, and final model recovery from integrated data. A quadrant analysis t...

-A detailed study of conditions leading to fiber fracture during the consolidation of Ti-14wt %A~21 wt%Nb/SiC (SCS-6) composite monotapes has been conducted. For this continuous fiber reinforced composite system, the incidence of fracture increases with consolidation rate at higher process temperatures. Increasing consolidation temperature at a fixed pressure reduces the number of breaks per un...

During tube hydroforming process, the friction conditions between and die have a great importance on material plastic flow distribution of residual stresses final component. Indeed, three-dimensional finite element model process in case square section has been performed, using dynamic static approaches, to study effect both induced by process. First, comparative numerical experimental results c...

In order to identify physical model parameters of a high-rise building, a new story stiffness identification method is presented based on a shear-bending model and the identification function. Although a shear building model may be the simplest conventional model for representing tall buildings, the system identification (SI) method using that model is not necessarily appropriate. This is becau...

The design of multi stage deep drawing processes requires the evaluation of many process parameters such as the intermediate die geometry, the blank shape, the sheet thickness, the blank holder force, friction, lubrication etc..These process parameters have to be determined for the optimum forming conditions before the process design. In general sheet metal forming may involve stretching drawin...

Cross-sectional deformation of double-ridged rectangular tube (DRRT) inevitably occurs due to the inhomogeneous deformation induced by external boundary conditions in rotary draw bending (RDB). Unreasonable factor combination would aggravate the cross-sectional deformation of DRRT. So, a powerful and efficient method combining Response Surface Methodology (RSM) and Non-Sorted Genetic Algorithm ...

die erlebnislyrik umfasst die gedichte, in denen es um die erinnerung eines lyrischen ichs an ein geschehen geht, wobei mit dem gedichtschreiben ein erinnerungsvorgang in gang gesetzt wird, der einen bezug zwischen dem erlebenden ich und dem geschehen schafft und damit ein unmittelbares erleben erzeugt. die speziellen mittel der lyrik wie reim, rhythmik, klang, melodie, wiederholung, bildsprach...
